1 Claim. 1

My presentinvention relates to improvements in buttons, more particularly to buttons compris ing. a cloth-covered top portion and a bottom portion, both of the said portions being held" together by anoverlapping margina1 curb provided on one portion thereof, and being perforated in the central part, and a web formed on the one button portion; the entire button structure being of such character as to permit of being sewn fast and tight to a foundation by passing thread and needle through the outer cloth covering; and the object of my improvement is, first, to prevent, by means of the said web, the thread from tearing the cloth, covering in the range of the sewnportion, and second, to afford aclose fitting of. the buttononto its f oundation.

The said button top portion preferably comprises a raised marginal curb to permit, when sewing on the button, of thecloth covering on the front side of the button being drawn inwardly, thus readily affording acorresponding ornamental form which in prior cloth-covered multiplebuttons only could be attained in a comparatively complicated way and manner by means of auxiliary parts and additional operations.

I attain such and related objects by the forms of button illustrated in the accompanying drawings, in which Fig. 1 shows a first form of cloth-covered button in cross-section, prior to being sewn on,

Fig. 2 is a top view of Fig. l, the central portion of the cloth-covering being cut out,

Fig. 3 a cross-section of such button sewn fast to a foundation fabric,

Fig. l a cross-section of a second form of clothcovered button, sewn to a foundation fabric,

Fig. 5 a top view of the button bottom portion, and

Fig. 6 is a cross-section corresponding to Fig. 4, comprising a modified detail of the latter form of cloth-covered button.

In the first form of invention (Figs. 1-3), the stamped and pressed metal top and bottom portions are denoted by I and 2 respectively. The top portion I, provided with the cloth-covering 3, overlaps, by its beaded and inwardly tapered rim wall 4, the outwardly tapered rim Wall 5 of the bottom portion 2, i. e. the said two portions are conically nested within each other. The bottom portion 2, otherwise in the form of a disc, comprises four sewing perforations 6 in its central portion. A raised marginal rim or curb I is formed on the top portion I by a conical inward pressing, and the cloth-covering 3 is stretched over the hollow space formed by the said pressing in 2o eorrespondingtc thetwo metallic button 8-, limited-byabeaded edge. 9 .which abuts against the bottom portionl and thusfstiifens the entire stru ture... l hasaidfour. sewing perforations (5 are situated within the range of the-central openingdprovidedmrthe topportion I.

The, cloth-covered button described is sewed to; the-- cloth foundation II- by, a. thread II], as.

shown in. Fig. 3.. Aswill be seen, the sewing thread I.il,, dr,awn: manually. through the clothcovering-3,, further.- passes. through the central opening-8 of, the topportion- I andthroughthe perforations.firoithe-bottom-portion 2 back onto tbezfrontside of :thabut-ton.

Inez-button described is assembled by means of a ,so-called:buttongmachinewhich comprises dies portions and mechanically movable with reference to each other so. that the said two portions are rigidly combined, inclusive of the cloth-covering, in the manner prescribed. The manufacture of buttons according to my present invention thus is substantially simplified in comparison with prior socalled fancy buttons, and requires a smaller number of molding dies and component button parts. The present buttons, therefore, save work and material.

In the second form of invention (Figs. 4-6), the two button portions I and 2 may be interlocked by mere manually applied pressure. The button top portion I, provided with the clothcovering 3, has a rearwardly and inwardly tapered marginal rim or flange 4 which terminates in an inwardly rolled beaded edge 4'. Two elongated, parallel perforations or slots 6, approximately of semi-circular form and separated by a web or bar 6' (Fig. 5), are provided in the bottom portion 2 opposite to the central opening 8 in the top portion I which construction makes it possible for the buttons to be sewed on either by hand or by machine. The bottom portion 2, provided with a serrated marginal rim 2 and formed by a disc, has four radial notches or slits I2, the number of which may, of course, also be greater or smaller. These slits l2 extend from the said edge slightly beyond an annular rib I3 pressed into the bottom portion 2 so as to subdivide the circumference of the latter into four lobes I4. Within the range of the latter, the resilience of the bottom portion 2 thus is correspondingly increased, while, on the other hand, the strength of the lobes I4 is increased by the annular rib I3. The

The clothecovering 3 isdiameter of the bottom portion 2 is so chosen, with regard to the resilience of the bottom portion I and to the inner marginal diameter defined by the inwardly rolled beading 4' on the top portion I, that, for the purposes of assembling the button portions, the bottom portion 2 may be easily sprung by hand into the top portion I. In such operation, the lobes [4 are first retained by the serrated edge 2' abutting against the beaded edge 4', undergoing a corresponding deflection, until the serrated edge 2' passes through the said inner marginal diameter, while the lobes I4 spring back, and becomes engaged back of the beaded edge 4' which is lined by the cloth-covering 3, thus firmly interconnecting the button portions. The cloth-covering 3 on the top portion I thus is located by the clamping action between the bead 4 of the overlapping edge 4 provided on the top portion I and the serrated marginal edge 2' of the bottom portion 2. When thus assembled the central portion of the bottom portion 2, containing the slots 6 and bar 6' is held against the limiting edge of the depressed portion of the top I at the opening 8.

The web 6' intermediate of the perforations 6 in the bottom portion 2, prevents a tearing or rending of the thread I!) and the cloth-covering 3 in the Vicinity of the place of sewing.

In the modification shown in Fig. 6, an annular rib or bulge I5 is pressed in the bottom portion 2, which i intended to cooperate with the beaded marginal edge 9 of the aperture 8 in the top portion I. Thus a guide is afforded, which facilitates the proper centering of the button portions when assembling same, andan abutment which prevents a relative transverse movement of the button portions. The radial slits l2, subdividing the bottom portion 2 into a plurality of lobes 14, are not extended down to the annular bulge l5 which thu is not interrupted, i. e. not weakened.

The fact that the manually assembled button according to Figs. 4-6 comprises only two hard or, respectively, metallic components, renders its manufacture and assembly particularly simple.

What I claim and desire to secure by Letters Patent is:

A button comprising a rigid back Wall having a pair of elongated parallel slots spaced apart leaving a free central bar in the plane of the wall and having a forwardly directed marginal rim, a rigid front wall having a rearwardly directed clamping flange as a continuation of its front, and formed with a central conical, depressed portion, which has an opening at its center, the limiting edge of which conical portion at said opening lies against the back wall, and said button having upon it front wall a piece of cloth which is held fast between the said clamping flange and marginal rim, and covers said central opening as well as the bar, which makes possible the sewing-on of the button by machine by threads which pass back and forth through the cloth overlying the center opening of the front wall and holds the center portion of the cloth cover drawn into the depressed portion of the front wall.
